Potential for ill-posedness in several 2nd-order formulations of the Einstein equations

By Simonetta Frittelli at
LogoDuquesne University
Second-order formulations of the 3+1 Einstein equations obtained by eliminating the extrinsic curvature in terms of the time derivative of the metric are examined with the aim of establishing whether they are well posed, in cases of somewhat wide interest, such as ADM, BSSN and generalized Einstein-Christoffel. The criterion for... Show more
